I like mine...
mon - chest
tue - cardio or rest
wed - legs (quads, hammies, light calves)
thurs - cardio and/or abs
fri - back, shoulders and traps
sat - arms
sun - calves and abs
Without the extra calf and ab work, and no cardio, I was doing:
mon - chest & abs
tue - off
wed - legs
thur - off
fri - back, shoulder & traps
sat - off
sun - arms
